So you can easily preform 12 sets all of which work the target muscle. For your leg routine do you do 12 sets of leg presses and thats it? i doubt it, you probably do isolation exercise that target leg exstensors, flexors, calves maybe even exercise for hip abduction and adduction. The back is the same way it takes different exercises to work the whole back. For instances if you do chin ups you dont work the lower back, if you do rows you are not working the lats. I just dont see how performing 12 sets of pull downs or rows works the entire back. just my .02$
